This introduces a `CollectionSource` trait as an alternative to `CollectionFilter` in `HTMLCollection`, allowing collections to provide elements directly via a custom iterator rather than filtering a full subtree traversal, which would otherwise be rather inefficient for smaller iterable sequences of options that can be determined without traversing the whole subtree again. The newly implemented `selectedOptions` attribute on the `<select>` element uses this to iterate only the element's list of options that are marked as selected. Testing: 14 assertions in the existing WPT went from failing to passing. Fixes #15522. --------- Signed-off-by: Jacob Adam <software@jacobadam.net>
